Bully with a black belt: Nate Diaz's top 5 submission victories

Nate Diaz will look to vanquish Conor McGregor for a second time when the two square off at UFC 202 on Aug. 20.

The Stockton, Calif., native won his first fight with McGregor via rear-naked choke at UFC 196. The victory was Diaz's 12th by submission.

In anticipation of the highly touted rematch, here are five of Diaz's best moments from his guard (in chronological order):

Junior Assuncao at UFC Fight Night 11

In his second fight in the UFC, a young Diaz gave fans a crash course in Brazilian jiu-jitsu (BJJ) in just over four minutes.

Assuncao proved a valiant opponent, rolling and transitioning seamlessly to maintain control of Diaz's back. A scramble brought the fight back to the feet, where Assuncao was treated to some Stockton boxing. Diaz dropped the Brazilian and followed the knockdown with a modified guillotine choke for the win.

The fight, which came at a time when casual fans were still unfamiliar with the intricacies of BJJ, was the first of many Diaz started slowly, only to the weather the storm and steal a victory.

Kurt Pellegrino at UFC Fight Night 13

As in his fight with Assuncao, Diaz took some time to get going, giving up his back seconds after the opening bell.

Pellegrino, a solid jiu-jitsu practitioner himself, alternated between controlling Diaz's back and ground-and-pound in the opening stanza. The tide turned in the second as Diaz got busy from his guard. When Pellegrino attempted a slam, he sealed his own fate, stumbling into a triangle choke.

In a quintessential Diaz moment, the Stockton son flipped two birds and flexed his arms in victory ... with Pellegrino still locked in the choke.

Melvin Guillard at UFC Fight Night 19

Sure, Guillard's submission defense has been notoriously pedestrian, but that doesn't make Diaz's victory any less impressive.

In what was becoming a pattern in his fights, Diaz was trailing early, as Guillard needed all of five seconds to drop him with a right hook, and relied on head movement to slip his punches.

After Diaz found his boxing range in the second, Guillard backed toward the cage in a botched rope-a-dope attempt, then desperately shot for a takedown, exposing his neck. Diaz turned the opening into the same modified guillotine choke he used on Assuncao for the win.

Takanori Gomi at UFC 135

After two straight losses at welterweight, Diaz returned to lightweight with a vengeance.

Contrary to the other fights on our list, this one was all Diaz as he immediately took the center of the octagon and tuned Gomi up with his boxing. The troubled Gomi managed to throw Diaz on his back, only to be caught in an armbar. All in four and-a-half minutes.

Jim Miller at UFC on FOX 3

Diaz made surprisingly short work of Miller in their main event matchup.

After a highly contested first round, Diaz couldn't miss in the second, doubling Miller's striking output both in the clinch and in the center of the cage. Just as he did with Guillard, Diaz converted a takedown attempt into a guillotine choke, handing the ever durable Miller his first career submission loss.

The win earned Diaz a shot at the lightweight title against then-champion Benson Henderson.
